I have a 1980 vintage depth sounder I built for my boat. Unfortunately I don't
have the M/N, but they only made one non-portable model. I would like to
readjust the circuit because I changed the transducer. I remember that there
is a transformer T1 or T2, and a coil L1 or L2 that need to be adjusted, but I
don't remember in which order. Does anyone have any idea where information from
manuals can be accessed? Thanks in advance.
